Activating hidden metrological usefulness
Géza Tóth, Tamás Vértesi, Paweł Horodecki +1
We consider bipartite entangled states that cannot outperform separable states in any linear interferometer. Then, we show that these states can still be more useful metrologically…
Bounds on bipartite entanglement from fixed marginals
Giuseppe Baio, Dariusz Chruscinski, Pawel Horodecki +2
We discuss the problem of characterizing upper bounds on entanglement in a bipartite quantum system when only the reduced density matrices (marginals) are known. In particular, sta…
The experiment paradox in physics
Michał Eckstein, Paweł Horodecki
Modern physics is founded on two mainstays: mathematical modelling and empirical verification. These two assumptions are prerequisite for the objectivity of scientific discourse. H…
Operational causality in spacetime
Michał Eckstein, Paweł Horodecki, Ryszard Horodecki +1
The no-signalling principle preventing superluminal communication is a limiting paradigm for physical theories. Within the information-theoretic framework it is commonly understood…
